Dive into the island's best family activities

Marathon is well-known for its laid-back and family-friendly atmosphere. It's tempting to spend your vacation days sprawled out on Tranquility Bay's private 2.5 acre white-sand beach with its range of water-based activities available on-site, or making a splash onsite in one of our three swimming pools. But once you venture beyond the resort you will soon discover Marathon attractions and activities to keep all family ages entertained.

You can swim with dolphins at the Dolphin Research Center and learn all about the characteristics of this majestic marine creature. Nature-lovers will also have fun at the Turtle Hospital which is home to rescued sea turtles and offers guided tours for kids to get behind the scenes and learn all about the rehabilitation programme. Visit the new Aquarium Encounters Florida Keys for interactive adventures with sharks, sting ray and more. Kids will also love the Wild Bird Center which features a sanctuary and visitor center, searching for Key deer on Big Pine Key, snorkeling the crystal-clear waters during day visits to the island's best beaches.

Beautiful beach houses

Sprawl out in style this summer in one of our spacious two or three bedroom beach houses and cool down on your own private balcony overlooking the natural beauty of the Gulf of Mexico.  With plenty of home-from-home luxuries, including flat screen TVs, your family beach house offers plenty of space for switching off and recharging after a lively day of family fun.

Keep cool and indulge

You can stay refreshed around the resort by taking a dip in one of our sparkling pools, all surrounded by beautiful tropical gardens, or stretching out on our soft-sand beach. Perfect for all the family, our beach-side TJ's Tiki Bar will add to your moment of cool with its selection of ice-cold drinks and delicious snacks. Butterfly Café is also popular for lunch, and makes an ideal setting for evening dinner after an action-packed day of family fun.
